Embodiment Construction

[0023] Embodiments of the present invention will be described. figure 1 The numerical control device 20 in the machine tool 10 controls the machine tool 10 to perform cutting processing on the workpiece (cutting object) held on the upper surface of the table. The left-right direction of the machine tool 10 is the X-axis direction, the front-back direction of the machine tool 10 is the Y-axis direction, and the up-down direction of the machine tool 10 is the Z-axis direction.

[0024] The machine tool 10 is a vertical machine tool that moves a tool attached to a spindle extending in the Z-axis direction in the X-axis direction, Y-axis direction, and Z-axis direction relative to the workpiece held on the upper surface of the table. To process the workpiece (drilling, tapping, side processing, etc.). The machine tool 10 has a spindle mechanism, a spindle moving mechanism, a tool changer, and the like. The spindle mechanism has a spindle motor 12 which can rotate the spindle on ...

Abstract

The present invention relates to a numerical control device capable of indicating an execution time taking into account an operation time of a machine tool. When workpiece machining based on the numerical control program is started, the numerical control device measures the time spent on closing the door of the machine tool, then the numerical control program is executed, and the workpiece is cut. In the numerical control program execution process, the numerical control device measures the execution time, and in the workpiece cutting process, the numerical control device measures the cutting time. When the execution of the numerical control program is finished, the numerical control device measures the time for opening the door of the machine tool. The numerical control device displays the cutting time and the door opening and closing time on a display screen. The numerical control device records including the opening and closing time of the door in a display column of the execution time, and displays the sum of the execution time and the opening and closing time of the door.

Description

technical field [0001] The invention relates to a numerical control device for controlling a machine tool for processing workpieces. Background technique [0002] The numerical control device controls the machine tool based on the numerical control program. The numerical control device described in Japanese Patent Publication No. 4312047 is capable of measuring the execution time of a numerical control program and presenting it as the time required for workpiece processing. It is possible for a manager to manage production using the machine tool in consideration of this time. [0003] As far as the machine tool with automatic opening and closing door is concerned, when starting to control the machine tool, the door is closed first, and then the numerical control program is executed to process the workpiece. After processing, the numerical control device opens the door to end the control of the machine tool. This numerical control device has a problem that the actual time ...
